Form forms in ASP. NET cannot be nested. asp. netform

I am very sure that there can be multiple form forms in ASP. I used to do this. In the background Classification Management page, add and modify the form on the same page, in this way, two form forms are used to submit the server code for processing.

After testing, ASP. NET can also have multiple form forms on a single page, for example, the following code:

<Form id = "form1"> </form> <form id = "form2"> </form> <form id = "form3"> </form>

However, form forms cannot be nested. For example, the following code is incorrect:

<Form id = "form1"> <form id = "form2"> </form>

In ASP. NET, when there are multiple form forms on the page, only one form can have the runat = "server" attribute; otherwise, an exception occurs. This is a common mistake in ASP. NET programming!

In ASP. NET programming mode, two or more form forms appear on a page. The function of submitting code to the server can all be done through an outermost form. There is no need to do so much. This is also a difference between ASP. NET and ASP!

I hope you can remember this!
